Given numbers are 121,642,887,236,214

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 121,642,887,236,214 is 8130664212.

Find LCM of 121,642,887,236,214 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 107 x 121 x 3 x 887 x 118 x 1 = 8130664212

Therefore, the lowest common multiple of 121,642,887,236,214 is 8130664212.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

121 x 642 x 887 x 236 x 214 = 3479924282736

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

121 : 1, 11, 121

642 : 1, 2, 3, 6, 107, 214, 321, 642

887 : 1, 887

236 : 1, 2, 4, 59, 118, 236

214 : 1, 2, 107, 214

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,642,887,236,214, is 1.

Now, the common factors can be found like this.

121:11x 11

642:2x 3x 107

887:887

236:2x 2x 59

214:2x 107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 107 = 428

Therefore, the value for common factors is 428.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 3479924282736/(1x428)

LCM = 3479924282736/428

LCM = 8130664212

Thus, we can understand that the LCM of 121,642,887,236,214 is 8130664212.
